Industrially viable diffused IBC solar cells using APCVD dopant glass layers

Even though interdigitated back contact (IBC) architecture produces the most efficient solar cells, it is difficult to make them cost-effective and industrially viable. Therefore, single-sided atmospheric pressure chemical vapor deposition (APCVD) is investigated for the fabrication of IBC solar cells because it reduces the overall thermal...

In Situ Annealing of Boron-Doped Amorphous Silicon Layers Using APCVD Technology

In this work, we developed an in situ annealing process to crystallize boron-doped amorphous silicon [a-Si(p+)] layers deposited by atmospheric pressure chemical vapour deposition (APCVD) to form boron-doped polycrystalline silicon [poly-Si(p+)] layers. The influence of the temperature profiles during a-Si(p+) inline deposition on structural,...
